I don’t see how that is the Yuzo teams problem though, it’s the same argument people use with firearms, just because the emulator can be used to emulate contribute piracy doesn’t mean that it was made with the intent to. How would you recommend the Yuzo team actively block non-released games/restrict it down to only legal use? They used the telemetry data that they recieved to better improve their own platform, honestly it doesn’t really matter what that data is. The issue is fully at the user who used the tool illegally, not the developers of the tool.
God I hate current copyright law, in my opinion they need to do seething similar to the legal systems “when acting as an official” law and just have them exempt from copyright/privacy suits. This happens with every emulator and it’s generally used as a scare tactic to make the devs close shop.
